In the original article, there was a mistake in the legend for **Table 2** as published. The incorrect legend reads as “**** ST+EMS= strength training combined with electrical muscle stimulation.” The correct legend should read as 2 “BW+WB-EMS: body weight associated with whole body electrostimulation****.” The correct legend appears below.
In the original article, there was a mistake in **Table 2**. **The lean mass signs †# need to be removed, since there was no statistical difference between pre versus post**. The corrected Table 2 appears below.

Alterations on body composition and functional fitness after 6 weeks of strength training combined with electrical muscle stimulation.
Values expressed in mean ± standard deviation. BW+WB-EMS = body weight combined with electrical muscle stimulation; MD[95% IC] = mean difference and 95% confidence interval.
Significantly greater than the corresponding pre-intervention value (p < 0.05).
Significantly greater than the control group (p < 0.05).
In the original article, there was an error in the first paragraph of the **Results** section It currently reads as “No differences were found in baseline parameters for any outcome parameters. As presented in Table 2, the values of sitting-rising test, arm curl, 6-min walk test, and handgrip strength were different from the pre-intervention value and the control group. However, the values in the stationary march test, and back scratch test, left and right side, were different only for the control group. No differences were found in the 8 feet up-and-go test.”
The paragraph should read as “As presented in Table 2, significant differences were found in baseline parameters between the control group and the BW+WB-EMS group for the stationary march test and the Back scratch test. The values of sitting-rising test, arm curl, 6-min walk test, and handgrip strength were different from the pre-intervention value and the control group. However, the values in the stationary march test, and back scratch test, left and right side, were different only for the control group. No differences were found in the 8 feet up-and-go test.”
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
